The following diagram shows the flow diagram (execution process) of a while loop in Java -Here, key point of the while loop is that the loop might not ever run. When the expression is tested and the result is false, the loop body will be skipped and the first statement after the ...
Abreakstatement is used to exit the loop in awhile-loopstatement. It is helpful in terminating the loop if a certain condition evaluates during the execution of the loop body. inti=1;while(true)// Cannot exit the loop from here{if(i<=5){System.out.println(i);i++;}else{break;// E...
The condition num <= 5 ensures that the while loop executes as long as the value in num is less than or equal to 5. The execution of the loop stops when condition becomes false, that is, when the value of num reaches 6. The first statement within the body of the loop calculates the...

In the last tutorial, we discussed while loop. In this tutorial we will discuss do-while loop in java. do-while loop is similar to while loop, however there is a difference between them: In while loop, condition is evaluated before the execution of loop
Java Loop With loops, you get to leverage the power in the computer. Working with computers, you quickly learn that they lack any sort of insight to solve problems on their own. On the other hand, the computer is happy to execute the code we specify a million times over, which is its...
In computer programming, loops are used to repeat a block of code. For example, if you want to show a message 100 times, then you can use a loop. It's just a simple example; you can achieve much more with loops. In the previous tutorial, you learned about Java for loop. Here, ...

Android应用程序因while循环而崩溃请阅读有关activity life-cycle的内容。您不能在onCreate中调用长时间运行的任务，并期望它们显示除ANR崩溃之外的任何内容（您的onCreate方法使用所有这些sleep语句阻塞UI线程，并在它到达onStart和onResume阶段之前生成ANR崩溃，在那里它实际显示活动）。如果你想让UI动态地改变，你可以...
